VICTOR E. COZINE, OF GLOVERSVILLE, NEW YORK.

TIME-CONTROLLED DRAFT-REGULATOR.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed March 4, 1910. Serial No. 547,287.

To all whom 'it may concern:

Be it known that I, VICTOR E. Cozmn, a citizen of the United States, residing at Gloversville, in the county of Fulton and State of New York, have invented certain new and useful Improvements in Time-Controlled Draft-Regulators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements in draft regulators and more particularly to a time controlled draft regulating device which is adapted to be automatically actuated by the operation of the alarm of a clock to open or close a draft damper.

Another object resides in the provision of l a very simple device of the above character which may be constructed and installed at a minimum expense and is extremely posi tive and efficient in its operation.

Vith these and other objects in view, the

inventionconsists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which-- Figure 1 is a side elevation of my improved draft regulator showing the same connected to the damper arm, the damper being closed; Fig. 2 is a similar view showing the device when arranged for automatically closing the damper; Fig. 3 is a sec tion taken on the line 33 of Fig. 2; and Fig. 1 is a detail perspective view of the releasing pin and the supporting frame therefor.

Referring more particularly to the drawings 5 indicates a case which, as shown in the drawings, is of substantially rectangular form, though it will be obvious that the same may be of any other desired form. This case is provided with a hinged door 6. A transverse partition 7 divides the case 5 into two compartments. The smaller of said compartments is adapted to receive an ordinary alarm clock 8. In the other of the compartments spaced vertical supports 9 are secured to the bottom of the case and have mounted for rotation between their upperof said wire passing around the pulley and having a ring secured to its end which is adapted to receive a hook 1'11 secured to a wire or other flexible connection 15. The other end of the wire 15 is secured to a drum 16 which is carried upon the end of the alarm winding shaft. The alarm is wound by turning the drum to the left in the usual manner, and such alarms being old and well known in the art the same will not here be set forth in detail.

From the above it will be obvious that when it is desired to open the damper at a predetermined time, the alarm may be wound in the usual manner, and the ends of the cables 12 and'15 connected, the other end of the cable 12 being attached to the damper arm. The alarm is now set by adjusting the dial on the clock face, and when such time is reached the operation of the alarm will rotate the drum to the right, thus winding the wire 15 thereon and moving the wire 12 over the pulley 10. The damper plate will, therefore, be lifted, thus opening the draft.

In order to utilize the device for the automatic closure of the damper, I provide a substantially U-shaped frame 17 which is arranged within the casing, said frame being formed by bending a metal bar between its ends, as clearly shown in Fig. 1, the ex tremities of said bar being attached to one side and the top of the case by screws or other suitable fastening devices. The parallel arms of the U-shaped frame are provided with openings in which a releasing pin 18 is slidably mounted. This pin is formed upon one end with an eye for the attachment of the hook 1 1 on the end of the wire 15. The other end of the pin extends a considerable distance beyond the U-shaped frame and is adapted to receive the ring socured to the upper end of the wire 12. This arrangement is clearly shown in Fig. 2 of the drawings and it will be obvious that after the alarm has been set and is operated by the clock movement, the winding of the wire 15 upon the drum 16 will cause the retraction of the pin 18 in the arms of the U- shaped frame 17. Thus the upper end of the wire 12 will be released, and the damper plate 13 will close by gravity.

From the foregoing it will be seen that I have provided a very simple and efficient time controlled damper operating device which is applicable to various kinds of furnaces including coal, steam, hot water, or hot air. The case may be secured to the ceiling, or suspended therefrom by means of suitable hangers so that the same will be approximately on a level with the eye of the operator. The attachment of the parts for the opening and closing of the damper plate may be reversed, or, in other words, the connection of the wire 12 to the releasing pin 18 may cause the opening of the draft, as in some furnaces the draft plate opens by gravity when released, and the connection of the cables 12 and 15 will close the damper plate instead of open the same as previously described.

By the use of my improved draft regulating device, the care and attention heretofore required in the operation of furnaces is to a large extent eliminated. The device is also very durable in construction and may be manufactured at a very low cost.

While I have shown and desired the preferred form of my invention, it will be understood that the same is susceptible of many minor modifications Without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described the invention what is claimed is:

In a device of the character described, the combination with a casing and an alarm clock arranged therein, of a U-shaped frame formed intermediate of the ends of a metal bar, said bar having its extremities secured to the inner walls of the casing, the arms of said frame having openings therein, a; re leasing pin slidably mounted in said openings, a wire attached to the draft plate and extending through an opening in the bottom of the casing, the upper end of said wire being removably engaged over the end of said pin, and a flexible connection between the alarm shaft and the other end of said releasing pin whereby said pin will be retracted in the frame upon the operation of the alarm to release said wire therefrom, substantially as and for the purpose set forth.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

VICTOR E. COZINE.
